Sectional Area : 4.53 cm2
Unit Weight : 3.6 kg/m
How to read this CHS reference
CHS means circular hollow section. The designation identifies a round, hollow steel profile, while the size notation indicates the listed diameter and wall thickness. In this entry, the diameter is 48.3 mm and the thickness is 3.2 mm.
The sectional area is the cross-sectional steel area reported for the profile. The unit weight expresses the listed mass per metre and can support material takeoffs and drafting coordination. These values should be used together with the applicable design checks rather than as a substitute for member, connection, or stability verification.
Standard reference
This entry refers to EN 10210-2:2006-04, which addresses dimensions, tolerances, and sectional properties for hot-finished structural hollow sections. It supports the associated technical delivery requirements identified in the source content. Review the applicable project documents and adopted standard requirements before fabrication or design approval.
CAD and drafting resource
The downloadable DWG provides a practical starting point for drawings and layout work. Check the imported geometry, units, layer conventions, and drawing scale against the project template before issuing or manufacturing from a CAD file. Related resources may include DWG steel sections, structural detailing, and hollow section connections.
